shall have a very large capacity and at the same time have a low center of gravity, whereby danger of tipping or derailing of ,the car in transit will be minimized, and also to provide a structure which will have the necessary rigidity and resistance to all' stralns which .occur 1n servlce, whether ofI pulling, buiiing or twisting that tendu'to spring the joints of the tank and cause leakage.

Still another object of my invention is to 'y 0 ered as composed of a central or intermedljprovide a tank car construction having a tank, a portion of which is set below the line of draft and having its bottom portion or bottom plate secured lto tlie body bolsters, and at the same time avo ding the use of center sills within the t-an and in which the buiiing and pullingstrains on the bottom plate of the tank are relievedby longitudinal sills disposed exteriorly of the tank spaced therefromand preferably in a plane above the lowest portion of the bottom tank plate between the body holsters.

Other objects will in part be obvious or hereinafter morespecifically explained, and the invention furthermore consists in the improvements in' the parts and devices and in the combinations of lparts and devices hereinafter shown and described or claimed.

In the accompanying drawing forming a part of this specification, Figure 1 is a side elevation of a tank car embodying my improvements. Fig. 2 1s an end view of the structure shown 1n F-1g. 1. Flg.` 3 1s a transverse, vertical section, taken von the line 3 3 of Fig. 1, the car frame being omitted. Fig.

Fig. 7 is a transverse section, upon an enlarged scale, taken substantially on the line 7-7 of Fig. 9. Fig, 8 is a similar sectional view, taken on the l1ne 8-8 of Fig. 9.. Fig. 9 is a vertical longitudinal section, upon an enlarged scale, taken at one end of the car and centrallythereof. Fig.l 10 is a horizontal, sectional view of one end o`f the i tank.` 11 is a plan view of the car frame at one end of the car, the tank being removed. Fig. 12 is a vertical section, upon an enlarged scale, taken on' the line 12-12 of Fig. 11. Fig. 13 is a detail, sectional view, showing the manner of attaching the hand rail to the foo-t board.

'In the drawing, 20 designates the tank which is of cylindrical shape, and in the structure which I have devised, -will have aA capacity larger than that of any tank car which has been in commercial use, so farl as I am aware, the capacity of the tank being upward of fourteen thousand gallons. For

a the purposes of a clearer understanding of the description, the tank 20 may be considf ate main portion 21 andred-uced ends '22, 22. The central portion 21 ofthe tank from one body bolster 23 tothe other, has its lower portion .24, which may beconsidered as a single bottom plate, extended below the-line of draft in'order that the center of gravity of 'the tank may be lowered to insure proper safety. Each reduced end 22 ispreferably tapered, as' viewed? in horizontal cross sec.- tion,-Fig.`10,-andthe upper plates thereof are secured to the 1nain por ti0n.21 as by a series of .rivets 25, see' Fig. 1. Each end 22 is furthermore provided with a bottom plate 26, a portion 27 of which'i's flattened and is disposed horizontally, and which rests on.

inner edge 29 of each bottom lplate y26 yisa downwardly extending port-ion 3() projectf ing within the main tankv portion 21, and having its inner edge 29 secured to' thenbottom plate 24 asby rivets 31, whichas-shown in Fig. 9 extend in acurved'line,and-this junction between the endl ofthe bottom plate 26 with the main bottom plate 2d is removed from the edge 32 of the pl: 1.te24, therebyleaving aspace between theportion- 30 and adjacent portions of the bot-tom plate 26, and the plate 24. The bottom plate 24 has each of its free ends securedas by rivets, 33

lcover these joints with interior patches or to employ `some other device. By forming this junction exteriorly ofthe containing portion of the tank, or so that t-he rivets or othersecuringl means do not come in contact with the contents, I do away with the necessity for patches and provide a structure whereby excessive and unusual strains may easily be withstood wit-hout dangerof causing leaks, and at the-same time, the circular flange laterally supports and stiffensv `each end of the main tank bottom plate.

Each body bolster 23 comprises preferably a steel casting having a web provided with a king bolt socket 36 suitably braced, said web having the saddle 28 extending outwardly therefrom and the flange v34 formed on` the inner side thereof, and the web may also be provided with perforations 37 whereby access'may be had to the space between the bottom plates of the main and' end sections of the tank. Also formed on each body bolster are outwardly projecting spaced flanges 38 located below the saddle 28, said flanges 38 having secured theretodraft sills 39, the latter being preferablygin the form of channels. The botf tom plate of each end is spaced from the draft sills, as clearly shown in Fig. 9, and attached to the ends of the draft sills are end sills 390 secured to the draft sills as by means of angle plates 40.- Platform plates 41 are riveted to the end and draft sills and extending upwardly Itherefrom are spaced plates 42 securely-attached toV the heads 43 at each end of the tank to properly strengthen and brace the ends of the tank.

Longitudinal. sills 44, preferably in the form of Z-bars, extend between the end sills and are securedto the-body holsters as at 45, said sills 44 being located above the lowest line of the bottom plate of the main portion ofthe tankl and adjacent but preferablyspaced from the sides of the tank.

\ A plurality of spaced brace and supporting mitted to the sills. At each end o f the car are provided diagonally disposed braceirons 47, each extending from the junction of a draft sill and the end sill to a point on :the

longitudinal sills adjacent where the latter are secured to the body holsters (See Fig. 11).

The car frame structure just described is light, yet strong and efficient, and performs an important function in attaining the objects of my invention. Hitherto, in tank cars not employing center sills, all the buffing and pulling strains have been borne entirely by the tank plates, with the result that they soon spring leaks, but in the structure which I have shown, the strains, instead of being carried by the bottom tank plate, are transmitted to the longitudinal sills chiefly through the diagonal base members. Another object attained by using longitudinal sills exteriorly of the tank in tank cars where portions of the tank are disposed bclow the lineof draft, is that interior center sills are dispensed withand thus the capacity of the tank is increased and obstructions in the interior o-f the tank which prevent the ready outlet of the contents are avoided.

Located preferably at each of the four corners of the car are ladders 48, disposed lengthwise of the car and supported on extensions of the end sills and supporting irons 49. Each ladder is secured to the tank as by means of an angle plate 50. The running board or plat-form 52 comprises end portions extending between each pair of ladders at the ends of the-tank which are supported on cross irons 51, said cross irons 51 being secured to the ladders 48 and to the end of the tank. rIhe longitudinally extending portions of the foot-board are supported as by means of spaced brace angles 53 secured to the upper sides of the tank, said portions being furthermore additionally supported at the ends by means of the ladders 41.

Another featureof my invention is the novel method employed of supporting and securing the hand railL 54, which is held in spaced upright angle irons 55, each secured to the foot board or platform, preferably by means of an upper, triangular, angle plate 56 (see Fig. 5), and another angle iron 57 is secured to the inner side of the vertical flange of the upright and to the under side of the foot board. Additional cross brace irons 58 are secured to the uprights 55 and extend over the top of the tank. Hitherto, ithas been custoniar to attach the hand rail directly to the .tan i, especially when the foot board is disposed at the lower portions of the tank, thereby increasing the number of perfor-ations that must be made in the tank, and in such a structure it will be apparent that the severe pull on the` gripping member tends to tear the rivets from the tank on account of the leverage, butin my construction, the strain is taken entirelybythe-platform and any three feet inwardly from each body bolster or ata point beyond the journal box, where they serveas jacking blocks, and this location is particularly desirable .since in jacking.

the cars to removeI the trucks,'a solid foundation for the jack can be easily secured by layin a lank over the ends of the rail ties direct beneath the jacking blocks.

Push pole pocket castings 60 are secured to the longitudinal sills and to the body holsters, as clearly shown in Figs. 7 and 8, opposite the central web ofthe body bolster.

Hitherto it has been customary to locate thevpush pole pocket castings at the extreme corners of the cars, but this has proved disadvantageous, ,particularly ,on cars employing alight car frame, since in'pushing, the strainsI bend. the` ends of the longitudinal sills inwardly and upwardly.
